Educational Background

  • Ph.D., Computational Physics, Sheffield Hallam University, 2001
  • Master of Science, Engineering Physics, Sheffield Hallam University, 1998

Professional Background

  • 2001 - 2004. Post Doctoral Research Associate, Chemical Engineering Department, University of Pittsburgh.
  • 2004 - 2007. Post Doctoral Research Associate, Chemistry Department, Durham University (UK).
  • 2007 - 2009. Visiting Assistant Professor, Physics Department, Case Western Reserve University.

Area of Expertise/Research

  • My research involves using computers to solve complex physical problems. I write computer programs which mimic real experimental and natural systems. These computer simulations not only allow us to see what might happen if we make changes to a system, but also reveals insights that might otherwise be experimentally unobservable. For example, my simulations of polymer nanoparticles allow us to view drug diffusion from within a structure ten thousand times smaller than the thickness of a human hair - something which would be experimentally impractical.
